Eichler homes are architectural gems, but their signature flat roofs require different care than traditional pitched roofs. Whether you have an original tar and gravel roof or a modern foam system, proper maintenance extends roof life and prevents costly repairs.
Understanding Your Eichler Roof
Most Eichler roofs fall into one of these categories:
Original Tar and Gravel (Built-Up): If your home still has the original roof from the 1950s-60s, it’s likely past its expected lifespan. These roofs typically last 20-30 years.
Spray Polyurethane Foam (SPF): The most popular modern choice for Eichlers. Foam provides seamless waterproofing, insulation, and can last 30+ years with proper maintenance.
Single-Ply Membrane (TPO/PVC): Another modern option offering good durability and a cleaner appearance.
Silicone or Acrylic Coatings: Applied over existing roofs to extend life and improve waterproofing.
Monthly Maintenance Tasks
Check Drains and Scuppers
Flat roofs rely on drains and scuppers (side outlets) for water removal. Monthly checks prevent:
- Ponding water that degrades roofing
- Overflow during heavy rain
- Debris accumulation
What to do: Clear leaves, pine needles, and debris from drain baskets and scupper openings. In fall, check weekly during leaf drop.
Visual Inspection
Walk around your home and look up at the roof edges for:
- Visible damage or lifted areas
- Debris accumulation
- Signs of ponding (water lines or staining)
What to do: Note any concerns and schedule professional inspection if you see issues.
Seasonal Maintenance
Before Rainy Season (October-November)
This is the most important maintenance window:
- Clear all drains thoroughly
- Remove debris from roof surface (leaves, branches, dirt)
- Check seals around skylights and vents
- Inspect flashing at walls and parapets
- Schedule professional inspection if you haven’t had one this year
After Storm Season (March-April)
Winter storms can cause hidden damage:
- Walk the roof (if safe) or have it inspected
- Check for ponding areas that don’t drain
- Look for lifted seams or coating damage
- Clear any accumulated debris
Foam Roof Specific Care
If you have an SPF foam roof:
Coating Condition
The protective coating over foam is critical. Signs it needs attention:
- Exposed orange or yellow foam (coating worn through)
- Alligatoring (cracking pattern in coating)
- Chalking (white powder when rubbed)
Recoating Schedule: Most foam roofs need recoating every 10-15 years. Some may need it sooner depending on sun exposure and coating type.
Foam Damage
Foam can be damaged by:
- Bird pecking (they like the texture)
- Foot traffic
- Dropped tools or equipment
Repair: Small foam damage can be easily repaired by professionals before it leads to leaks.
What to Avoid
Never Do These Things:
Walk on the roof carelessly: Flat roofs aren’t designed for foot traffic. If you must access the roof, use walkway pads or have professionals do it.
Use pressure washers: High-pressure water damages foam and coatings. Gentle cleaning with a garden hose is fine.
Store items on the roof: Extra weight and sharp edges damage roofing. Keep mechanical equipment on platforms.
Ignore ponding water: Standing water for more than 48 hours after rain accelerates roof degradation.
Let trees overhang: Branches drop debris and can damage roofing during storms. Maintain clearance.
Signs You Need Professional Help
Call a flat roof specialist if you notice:
- Active leaks inside the home
- Bubbling or blistering in the roof surface
- Soft or spongy areas when walked on
- Visible damage to foam or membrane
- Persistent ponding that won’t drain
- Coating that’s clearly worn through
The Value of Professional Inspection
Even with good maintenance, annual professional inspection is essential for flat roofs. Inspectors can:
- Access areas you can’t safely reach
- Identify problems before they become leaks
- Check coating thickness and condition
- Recommend recoating timing
- Document roof condition for warranty purposes
Extending Your Roof’s Life
With proper care, modern flat roof systems can last decades:
- Annual inspection: Catch problems early
- Timely recoating: Don’t wait until coating fails
- Proper drainage: Keep drains clear
- Gentle cleaning: Remove debris without damaging surfaces
- Prompt repairs: Fix small issues before they grow
Finding Eichler Roof Specialists
Not all roofers understand Eichler homes. Look for contractors with:
- Specific experience with flat and foam roofs

- References from other Eichler homeowners
- Proper licensing for foam and coating systems

Eichler Neighborhoods We Serve
Walnut Creek: Rancho San Miguel
Rancho San Miguel contains one of the largest Eichler concentrations in Contra Costa County. These 1960s homes face specific maintenance considerations:
City of Walnut Creek permits require documentation for foam roof work. We handle all permit applications and inspections.
Title 24 compliance mandates reflective coatings with SRI 16+ ratings. This affects recoating product selection—not all coatings meet current energy standards.
Summer heat stress: Walnut Creek’s inland climate (regularly 95°F+) accelerates coating degradation faster than coastal Eichler neighborhoods. Plan for recoating every 10-12 years rather than the 15-year intervals common in cooler areas.
Original homes: Many Rancho San Miguel Eichlers retain original features worth preserving. We work carefully to maintain the architectural character while upgrading waterproofing systems.
Fremont and South Bay
The Tri-City area and South Bay (Palo Alto, Sunnyvale, San Jose) contain the largest Eichler concentrations in California. The Sunnyvale Eichler neighborhoods—Fairbrae, Ponderosa Park, Fair Oaks, and Cherry Chase—represent some of the best-preserved mid-century modern communities. Cupertino’s Rancho Rinconada is another significant Eichler enclave. Each microclimate affects maintenance schedules differently—coastal fog areas need different attention than inland heat zones.
East Bay
Mid-century modern homes in Berkeley and Oakland share many characteristics with Eichlers. While not all are Joseph Eichler designs, they benefit from the same flat roof expertise and maintenance approaches.
